med
30 min
Explore how to solve the problem of counting binary subarrays that sum to a given goal. Understand applying the sliding window technique to optimize solutions, enabling you to efficiently tackle similar interview challenges.

Statement

You are given a binary array, nums, and an integer, goal. Your task is to return the number of non-empty subarraysThis refers to a subarray, which is a contiguous part of the array. with a sum that meets the goal.

Constraints:

  • 11 \leq nums.length 3×104\leq 3 \times 10^4

  • nums[i] is either 00 or 11.

  • 00 \leq goal \leq nums.length
